## What is peer review?

One of the most important quality controls in science is peer review. This is a process in which other experts (peers) within the field assess a publication before it is published. They check:

- Whether the research has been carried out carefully.

- Whether the methods and conclusions are logical and well-founded.

- Whether the study is original and contributes to existing knowledge.

If an article does not meet scientific standards, it can be rejected or must be revised before it can be published. Peer review therefore helps to ensure the reliability and quality of scientific publications.
